C++ EDIT CreateWindow

Hallo,

When i, wane add a new EDIT child window which the user can type text from the keyboard.
a normal text box works, but when I challenge CreateWindowExW( EDIT ..)

and BUILD and run the program from my compute noting happens.

Do i miss the paint code or something.

//  Add a new TEXT imput box
//CreateWindow(TEXT("EDIT"),TEXT ("VALEU"), WS_VISIBLE | WS_CHILD | WS_BORDER ,10,10 ,200,25,hWnd, (HMENU) NULL,NULL,NULL );

// Add a new TEXT edit window

CreateWindowExW(WS_EX_CLIENTEDGE, TEXT("Edit"), NULL, WS_CHILD, 10, 10, 200, 25, hWnd, (HMENU) NULL,NULL,NULL );

Open in new window

the CreateWindowEx returns a window handle. you need to save that handle in order to call subsequent Windows functions, for example

ShowWindow(hwndEdit, SW_SHOW);

Open in new window

if you provide a parent window (you did with 'hwnd') and a valid ID (as HMENU) to the Create function, you would be able to retrieve the window handle of the edit box by calling

HWND hwndEdit = GetDlgItem(hwndParent, ctrlID);

Open in new window

where ctrlID is the ID that you passed as HMENU to the CreateWindowEx function.

I , understand your solution Sara,

but don't understand where i need to call hwndEdit in the code ,
where this you get "hwndEdit" from.

CreateWindowExW(WS_EX_CLIENTEDGE, TEXT("Edit"), NULL, WS_CHILD, 10, 10, 200, 25, hWnd, (HMENU) NULL,NULL,NULL );

ShowWindow(hwndEdit, SW_SHOW);

Hi,
CreateWindow returns it:

hwndEdit = CreateWindowExW(WS_EX_CLIENTEDGE, TEXT("Edit"), NULL, WS_CHILD, 10, 10, 200, 25, hWnd, (HMENU) NULL,NULL,NULL );
ShowWindow(hwndEdit, SW_SHOW);

from your code i see that you have created an mfc application.

if that is true you might consider to use a dialog-based mfc app rather than an SDI application with self-created controls.

you easily can test this option by creating a new mfc application project - say YopaWordEditor - and choose dialog-based as option. the generated mfc code already would generate a dialog resource for you and you easily could design a dialog form by using the resource editor.

I understand dialog-based mfc app ,
but i wanna LOW-LEVEL programming in the distend future build it in a intel FPGA micro controller.
And it's easier to write a c++ kernel

HWND hwndEdit;
...
..
hwndEdit = CreateWindowExW(WS_EX_CLIENTEDGE, TEXT("Edit"), NULL, WS_CHILD, 10, 10, 200, 25, hWnd, (HMENU) NULL,NULL,NULL ); ShowWindow(hwndEdit, SW_SHOW);
